How many variables can be accepted by one scanf() statement? - Answers

The scanf() function in C can accept multiple variables as input, with the number limited only by the available system resources and the specific format string used. Each variable must correspond to a specific format specifier in the format string, and the total number of variables is typically constrained by readability and manageability of the code. In practice, it's common to see scanf() handling anywhere from one to several variables at a time, but it can technically handle dozens if needed. However, for clarity and ease of maintenance, it's advisable to keep the number of variables reasonable.
